Definitions

  • the invention relates to a method for heating a furnace chamber, in which by means of a multi-fuel burner, a primary fuel and a primary oxidant and at least one secondary fuel stream are introduced into a furnace chamber, wherein the secondary fuel flow pneumatically guided by a delivery tube of the multi-fuel burner and in the region of the burner chamber facing the furnace chamber of the multi-fuel burner is deflected by introducing a gas stream introduced into a lower region of the delivery pipe.
  • Multi-fuel burners are used in particular in rotary kilns, for example in rotary kilns for cement production or for thermal waste utilization, and in particular allow the use of fuels of different calorific value during combustion.
  • the feeders or delivery pipes are designed as annular channels and / or run as mutually parallel pipes through the burner body.
  • a primary oxidant usually air (ā€œprimary airā€) is used.
  • a secondary oxidant (ā€œsecondary airā€) is fed directly into the furnace space via separate feeds outside the burner.
  • a high calorific fuel (with a calorific value of more than 10 kWh / m 3 or 30 MJ / kg) or a mixture of a high calorie fuel such as coal, oil or natural gas with a substitute fuel is usually used.
  • low calorific fuels means fuels which have a lower calorific value than natural gas. Examples of low calorific fuels are gaseous fuels with a calorific value of less than 10 kWh / m 3 , such as biogas, city gas or mine gas, or solid or liquid fuels with a calorific value below 30 MJ / kg.
  • substitute fuel is to be understood here as meaning all non-fossil fuels, in particular fuels derived from waste.
  • the range of alternative fuels used ranges from solvents, tire and wood chips, sewage sludge, rejects, shredder material from plastics processing or animal meal to processed waste from households, industrial and commercial enterprises, as well as renewable raw materials.
  • substitute fuels such as shredded plastics
  • shredded plastics for technical and economic reasons only to grain sizes of about 10 to 20 mm diameter are processed, they have a significantly worse flight and burnout than, for example, a finely ground coal.
  • these materials contain a wide variety of ingredients and moisture contents, and the particle size distribution extends over a wide grain band. This results in large, heavy and irregularly shaped particles in particular falling onto the clinker bed before they are fully reacted and triggering chemical reactions there with the feed substance.
  • a device for conveying pneumatically conveyed secondary fuels in particular for rotary kilns is described which comprises a central conveyor pipe having an outlet opening for the pneumatically conveyed fuels in the furnace chamber at the burner mouth.
  • a gas supply line is provided, which immediately (as viewed in the flow direction) opens in front of the outlet opening in a direction obliquely forward, ie in the direction of the outlet opening, directed from below into the interior of the conveying tube.
  • air is introduced at high speed through the gas supply line in the delivery pipe.
  • the supplied air flow encounters the flow of the secondary fuel, whereby the fuel particles passing through the air flow experience a corresponding impulse, which changes the trajectory of the fuel particles:
  • the fuel particles no longer leave the conveying pipe parallel to the conveying axis, but are ejected obliquely to the conveying axis.
  • the gas supply line (s) is / are preferably arranged obliquely forwards with its end section (s) leading into the delivery line, so that when the gas flow encounters the secondary fuel flow, the particles of the secondary fuel are simultaneously exposed to an upward and a forwardly directed impulse component , At the same time, part of the oxygen-rich gas penetrates into the secondary fuel stream and mixes with it. Another portion of the oxygen-rich gas forms below the Kliparabel of the secondary fuel from a zone of oxygen-rich gas, in which the particles of the secondary fuel inevitably sink when passing through their parabolic parabola.
  • the trajectory and time of flight of the secondary fuel extend within the furnace space.
  • the proportion of substitute fuels in the energy mix of the multi-fuel burner can be significantly increased and the proportion of high quality primary fuels can be correspondingly reduced, whereby a considerable cost savings compared to a operation with multi-fuel burners according to the prior art can be achieved.
  • Essential for the invention is in particular that the secondary fuel is exposed as long as possible as oxygen-rich atmosphere when passing through the furnace chamber.
  • a preferred embodiment of the invention provides to enter further oxygen-rich gas in a region of the furnace chamber, which in the operation of the multi-fuel burner from Secondary fuel flow is passed through.
  • the entry of this additional oxygen-rich gas for example by means of a lance or more lances, which opens / lead out inside and / or below the conveyor pipe at the burner mouth and / or opens / open as a separate lance / n in the furnace chamber and on one of the from the burner mouth emerging stream of secondary fuel particles is passed through area.
  • oxygen-rich gas should be understood here a gas having an oxygen content of more than 50 vol .-%, preferably with an oxygen content of more than 95 vol .-%, more preferably with an oxygen content of more than 99 vol .-%.
  • the oxygen-rich gas is generated for example in membrane plants or cryogenic air separation plants and stored in an oxygen tank at the location of the multi-fuel burner.
  • the use of oxygen instead of air in particular also increases the temperature in the furnace chamber, in particular in the region of the burner mouth.
  • the high temperature also contributes to the efficient combustion of such secondary fuels, which have only a low calorific value of, for example, less than 10 MJ / kg.
  • secondary fuels of comparatively high calorific value when burned with pure oxygen lead to such high temperatures that the burner housing could be damaged. Therefore, in order to bring the method according to the invention into operation even when the furnace is charged with different secondary fuels and / or in the case of very inhomogeneous secondary fuel streams, it is advantageous that the oxygen content of the oxygen-rich gas can be regulated in dependence on measured or predetermined parameters of the combustion process in the furnace chamber.
  • a target value of the oxygen content is determined as a function of the secondary fuel used or of the temperature or a measured exhaust gas concentration in the furnace chamber.
  • the secondary fuel stream To envelop a swirling air flow, which also consists of an oxygen-rich gas.
  • the gas feeds for the swirl air and for the oxygen-rich gas used for the deflection can be connected to a common oxygen supply line, wherein in a variant of the invention, the respective oxygen contents are independently adjustable.
  • the respective gas supply line is equipped with an oxygen supply line and a supply line for air, which are each equipped with suitable valves which can be controlled by a control device.
  • FIG. 1 shows schematically a rotary kiln with a multi-fuel burner in longitudinal section.
  • the embodiment according to Fig. 1 shows a multi-fuel burner 1, at the burner mouth 2 radially outwardly an annular channel 3 for the supply of primary oxidant and radially inside an annular channel 4 for the supply of a primary fuel into a furnace chamber 5 opens.
  • the primary oxidizer is usually air or an oxygen-enriched gas with an oxygen content of 22 vol% and above.
  • the primary fuel is usually a high-calorie fuel such as natural gas, oil or a powdered solid fuel from coal or petroleum coke, but other substances are considered as primary fuels, for example mixtures of a high-calorie and a low-calorie fuel.
  • the multi-fuel burner 1 may have feeders not shown here, which are arranged below the horizontal center plane 6 of the multi-fuel burner 1 and serve to supply further gaseous, liquid or solid secondary fuels, such as animal meal, solvents, waste oil, etc.
  • a delivery pipe 7 is arranged for a secondary fuel, in particular for a secondary solid fuel, such as plastic shredder material, tire chips, waste wood or other particulate waste or other, usually low calorific, solid fuels.
  • a secondary solid fuel such as plastic shredder material, tire chips, waste wood or other particulate waste or other, usually low calorific, solid fuels.
  • an annular channel 8 for the supply of swirling air which is fluidly connected to a supply line 9 for oxygen.
  • the annular channels 3, 4, and 8 and the conveying tube 7 are arranged within the multi-fuel burner 1 parallel to its longitudinal axis.

  • the gas supply pipe 11 opens immediately before the burner mouth 2 from below with an obliquely upwards, ie in the direction of the furnace chamber 5 facing end portion 12 in the delivery pipe 7 a.
  • the end portion 12 allows the introduction of the gas flowing through the gas supply pipe 11 in the delivery pipe with an obliquely upward and the furnace chamber 5 directed towards pulse.
  • the end section 12 opens, for example, as a slot-shaped, in the lower region of the conveyor tube 7 in the circumferential direction extending opening in the wall of the conveyor tube 7, or the end portion 12 includes a plurality of opening into the conveyor tube 7 gas outlet nozzles with or without a narrowing flow cross-section , Furthermore, the end portion 12 can end flush with the inner wall of the conveying tube 7 or, as an additional deflecting flow obstacle, protrude into the interior of the conveying tube 7.
  • Fig. 1 shows the multi-fuel burner 1 in its installed state in a rotary kiln 13, for example, a rotary kiln for producing cement.
  • the furnace chamber 5 of the rotary kiln 13 shown only partially comprises a rotatably mounted drum 14, at the end face 15 of the multi-fuel burner 1 is installed.
  • the drum 14 is loaded with feed material 16.
